Mark 7:15-19

there is nothing outside the man which can defile him if it goes into him; but the things which proceed out of the man are what defile the man. [If anyone has ears to hear, let him hear.”] When he had left the crowd and entered the house, His disciples questioned Him about the parable. And He *said to them, “Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him, because it does not go into his heart, but into his stomach, and is eliminated?” (Thus He declared all foods clean.)
